When there’s friendliness, when there’s gentleness, when there’s openness, then the mind may start co-operating with us. Otherwise we tell the mind to behave in one way and it is going the other way and we get angry about it.
So it becomes a battle and becomes another big fight. Meditation for most people is a fight. Fighting the mind. I often tell meditators, you have enough battles in life, please do not make meditation another battle! So with friendliness we need to understand how our mind and body works, and then through that understanding, developing mastery is the next thing. When I spoke on loving-kindness I mentioned that one of the benefits is that when there is loving-kindness the mind becomes calm naturally.
